Will House Alarm Go Off If Battery Dies?

Having a home security alarm in your home is really important, given how the world has so many cases of robbery and other crimes nowadays.

Normally, these house alarms are usually powered with electricity with a backup power source.

But you might wonder: “What will happen if these power sources die?” 

The primary power source of security alarms is electricity.

Fortunately enough, these alarms will still work even if there is no electricity.

This is because they are usually powered with a backup battery as well.

However, your house alarm will go off once you run out of battery.

Of course, it would mean that you are putting your house at risk, so it is really important to always make sure that your house alarms are always equipped with a full power source. 

What Happens If House Alarm Battery Dies? 

The battery of house alarms are usually meant as backup, in case the main source dies out.

These batteries are extremely helpful in keeping the alarms’ operations working even if there is no electricity. 

However, it does not mean that you should stay complacent.

Your battery may still run out, and when they do, the whole house alarm will also go off.

This is why make sure that you are fully aware of the features of your house alarm system including its total battery power. 

Can a Low Battery Cause a House Alarm To Go Off? 

So, if a completely dead battery causes the house alarm to go off, what will happen if it is only in a low battery status? 

House alarms will normally send alerts or notifications that the device is low in battery.

This will alert you to replace your security alarm’s battery.

In a case where your house alarm has low battery, it may even cause an alarm to go off as well. 

Worst case scenario, it may also cause a false alarm.

For the very first few false alarms, it might startle you or throw your house into chaos.

If repeated, you or other people in your house might start to dismiss these alarms, making it a dangerous situation once a real crime happens as you would no longer feel the urgency.
